    OBJECTIVE We aimed to evaluate the role of consolidative thoracic radiotherapy (TRT) in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS The clinical data for 151 patients with the diagnosis of ES-SCLC treated with consolidative TRT from six different hospitals from Turkey analyzed. RESULTS The median age of the patients was 61 years (range 36-83 years). The median dose of radiotherapy (RT) was 45 Gy (range: 30-66 Gy) applied in median 25 fractions (range 10-34 fractions). For 151 assessable patients, the median survival time (MST) was 14 months (range: 12.6-15.3). The patients who has complete response and partial response had 16 months, and 14 months of MST. In multivariate analyses prophylactic cranial irradiation (PCI) (p=0.011), female gender (p=0.017), and comorbidity (p=0.006) were found as significant parameters associated with survival. The MSTs were 12 months in patients without comorbidity, and 16 months for the patients with at least one comorbid disease. The patients who received PCI had improved MSTs when compared the ones without PCI (16 months vs. 12 months). There was a trend towards improved overall survival times in patients who received EQD2 >= 47 Gy RT doses (p=0.08). CONCLUSION Female gender, use of PCI, and unavailability of comorbid disease were associated with improved survival in ES-SLCL patients. There was a trend towards overall survival times in patients who received >= 47 Gy EQD2 doses; however, we believe that this statistical insignificance was related to our limited patient numbers.
